Used as a specialty crosslinking agent in advanced polymer synthesis, particularly in the development of functional hydrogels and bioconjugates. Its strained bicyclic alkyne structure enables efficient click chemistry reactions, making it valuable in bioorthogonal labeling applications for pharmaceutical research and diagnostic probes. Commonly employed to modify peptides, proteins, or nucleic acids with minimal interference to biological activity. Also utilized in controlled drug delivery systems where selective bond formation and stability under physiological conditions are required.
